The invention relates to a booster fan structure and an air-conditioner with the same. The booster fan structure comprises a first fan and a second fan. The first fan is provided with an air inlet and an air outlet. The second fan is provided with an air inlet and an air outlet. The air outlet of the first fan communicates with the air inlet of the second fan. The first fan and the second fan are in series connection. By means of the booster fan structure and the air-conditioner with the same, the air volume and air speed of the indoor side can be increased, the air supply distance can be prolonged, airflow achieves pressurized flowing, and the refrigeration effect is improved; complete machine power can be lowered, power consumption is reduced, and the energy efficiency ratio is increased; noise can be lowered, air can be exhausted out stably, and the product comfort is improved; and product reliability and competitiveness are enhanced.

A ventilator in a duplex structure is provided to increase ventilating capacity and reduce noise by coupling both of an axial fan and a centrifugal fan in a single ventilation system. A ventilator in a duplex structure includes a front cover(52) mounted with a streamline type first guide vane(51) in a bell mouth shape. An axial fan(10), a centrifugal fan(20) and a motor are coaxially arranged in sequence behind the front cover. The axial fan is mounted toward a room space to inhale room air. The centrifugal fan discharges the air inhaled by the axial fan to the outside at a high speed and simultaneously promotes the air suction of the axial fan to increase an amount of suction air, wherein the axial fan and the centrifugal fan rotate in the same direction by the motor. A second guide vane(22) in the shape of bell is mounted behind the motor for introducing the room air in the center and discharging the air circumferentially increased air suction and smooth air discharge. A housing is coupled with the front cover and receives all the above parts. The housing is formed with a spiral air guide path(40) integrating an outlet(56).
